You need to consider the size of wiring for oven. 4mm size should do the trick otherwise the wire will melt because it cannot take the heat with time.

Then the wattage.. 2780w/220v = 12.6A so rounding it to nearest number, then it would be 13A although it wouldn't hurt to play safe and use a 15A socket.

So if you going to use option 3, make sure the wire size is correct as well.

Hi guys, apologies if i hijacked this thread. Was just wanting to ask about the wiring for my new oven.

Purchased a built in electrolux EOB2400 rated at 2780w.

Ive been getting mixed opinions on the wiring,
1) to pull an additional cable from the DB. (Messy and least favourite option)
2) to just use a current plug.
3) to jus change the plug to a 15a plug.

Which of the above are not true?(sound like an exam?)  tongue.gif

Heres a photo of the actual plug point im planning to use. It will be connected to a soon to be built kitchen cabinet. It is not shared with any other socket other than a room socket used primarily for a table fan. The DB box unit is Marked In green as in the photo below.

Any the final questions are,

4) how much does an electrician charge for such services?
5) do you guys have any suggestions for electricians in subang or shah alam area?

Thanks in advance!

I say it's a matter of preference, budget for most.

European made appliances, I believe in their long-standing performance and stability due to experience. However, there is no basis as to why even china made, japan made or korean made appliances should deserve lesser interest as long as they perform reliably regardless of whether they will last as long as the european ones. So long as they can hold up to 5 years max, that is already good enough.

BMW and Mercs I will consider good stability on the road partly because the body is heavy and steering is stable unlike japanese, korean cars (depends on your driving ability with non european cars) but it is a real pain for maintenace after warranty period because they are european cars, the cost of maintenence is relatively higher in the long run unless one is prepared to upkeep the maintenance costs.

Always pros and cons, so I say, just buy what serves your purpose and nothing more.

It's easy to find out the AMP rating.

4.5kW = 4500W
Current Voltage provided by TNB = 220V-230V (I will use 220V for calculating instead)

4500W/220V = 20.45A (Round off to nearest digit which is 20A)

And what type is your electric hob? Induction or Vitroceramic?

Vitroceramic takes more energy than Induction to heat up so there's a slight difference between these two since Induction is considered energy saving. You may also use 25A to be on the safe side if you are still worried about the Amp.

For Oven, the kW or Wattage = 3.05kW or 3050W

3050W/220V = 13.86A (Round off to nearest digit which is 14A)
Then the nearest Amp socket, you will need is 15A.

That said, both oven and hob cannot share power links. Need to be solely dedicated power for each and you need to make sure the wire size for each power is 4mm and above because anything below that, the wire cannot handle the heat current and will fry the connection.

Hi experts.. Recently I've just purchased a oven Fotile model KQD50F-C2 and a electric hob model EEG75201. My wiring contractor was asking me the power points requirement on oven and hob. I read the specification of these models but it didn't specify the requirement for oven. Only stated for the electric hob is to be connected directly to 25A circuit breaker.

Then I called up the Fotile support service centre hotline for clarification. A very helpful and friendly technician says 15A for the oven and 20A for my electric hob would be sufficient. For the oven no issues but I questioned him that his advice on 20A power requirement for electric hod is contradict with their brochures which stated 25A. Then he says 25A also can.. I asked my wiring contractor, he says 25A is super big power! It makes me more confused rclxub.gif

Appreciate if anyone here can advice me should I go for 20A or 25A for the 4.5kW power requirement. Thanks in advance!  notworthy.gif

You're welcome.

By the way, I would suggest that if you have 2-4 cooking zones on your vitroceramic hob, you should not utilize all zones to cook at the same time because of the full power required to use all zones, and this more or less affects the overall power for the whole house provided by TNB. Balance between power distribution throughout the house I suppose, considering the AMP rating for aircon, heater as well.

Thanks for the detail explanation, S'aimer!
I have called a few electricians for clarification. Yes, you're right.. The wiring requirement is min 4mm. They say that 4mm would be sufficient for 25A. I'll ensure my contractor to provide 4mm each for my oven and vitro-ceramic hob separately.

My oven also came with the wire minus the plug.

You do not need to connect the wire that way.

What you need is a plug for the oven wire so you can plug that into the socket switch dedicated for oven use only. Has your contractor fixed the wall switches already?

Hi, just got my oven. Doing self installation, wiring had done by contractor.
The oven come with wire w/o plug.
My question is, can we connect the wire via the wire connector(those with screw on top and join then screw it) or I need to remove the oven wire and connect direct from wire to the oven connector terminal.

Oh.. I would prefer my oven to have a plug for the wire because frankly if need to send for repair, no need to dismantle the wiring. Yours will need to dismantle the wiring from the switch in this case right?

QUOTE(smon80 @ May 12 2015, 02:23 PM)
No, wow. They just lay the wire, said it can direct connect with the oven. Because my oven only arrive after 4 months renovated.
He just make a 20A switch control the power.

Your amp requirement is lower than mine. If I recall right, your total W = 7530W

I'm using a Teka vitroceramic hob and fotile oven.

Hob is 6.0kW or 6000W (25A-27A) & oven is 2.7kW or 2700W. Total W = 8700W so my AMP requirement is definitely higher.

Have new separate wiring dedicated for both oven & hob and yes both have their own plugs and socket switches.

I just told the electrician guy their wattage power and the Amp rating & he fixed it for me.

QUOTE(kinggerrard @ May 12 2015, 03:08 PM)
I had the same problem too about the wiring for oven and hob.. I have checked with Zeen and the technical support in Fotile.. They advised me to connect directly to the wiring from circuit breaker due to the high Amp requirement.

Seldom see a 25A socket. The closest is 32A Gang switch. Usually you can do a pairing with 15A socket switch with a 32A gang switch. Just tell that to your electrician.

Both the socket switch and gang switch have to be turned on at the same time for the hob to work. Mine is like this.



QUOTE(kinggerrard @ May 12 2015, 05:52 PM)
S'aimer, Can you find the socket switches with 25A?? I was told that the largest you can find in the market is only 20A. If you can find, pls do let me know

Because i extended my kitchen, so the new extension does not have any existing wiring. So have to put in new wiring for new sockets. Reconfigured the DB sorta.

The teka hob was below 2 k so meets the budget

QUOTE(kinggerrard @ May 12 2015, 05:48 PM)
Yep.. S'aimer, you're right.. Your amp requirements are higher than mine.. But the wiring should be same as mine which is 4mm pulled from the MCB separately (no sharing) to oven and hob each. The 4mm wiring can take up to 27A provided your electrician is using a good quality cable. I've asked my electrician to give me Mega cables for all the 4mm wiring. Btw, you have a very nice vitroceramic hob. Using Teka needs to have budget man  thumbup.gif

Direct from DB, cannot share with other appliances as it is only specifically for oven. Cannot also loop. Must be a new wiring, so your wireman has to lay a new wiring for oven.

Oven wiring must be at least min 4mm and above. As for switch amp power, check what is the amp power for the oven first.

You can calculate using the total amp for oven / 240V = xx Amp for switch
